I have root caused this test failure to the script assuming that tcgetattr()
... tcsetattr() ... tcgetattr() will always produce a configuration that is
bitwise identical to the previous configuration, which is not true with
normalization. This is an invalid use of the termios structure, which is
mostly an opaque data type, but gdb has a rather unique use case here in that
it is a debugger, and as such "it is not bitwise identical but has the same
function" might still be a problem for them.
Either way, this I believe is something that needs to be addressed in gdb;
either by using the kernel interface directly for the purpose of saving and
restoring, alternatively they may need some assistance in the form of a
dedicated save/restore interface.
I have filed this bug in the gdb bugzilla to address this issue:
https://sourceware.org/bugzilla/show_bug.cgi?id=33652
-hpa
This is a false positive, as the test is invalid: it expects the sequence
tcgetattr ... tcsetattr ... tcgetattr to produce a bitwise identical termios
structure, and that is simply not a valid assumption for *multiple* reasons.

If you need to cancel your Norwegian Air flight, do not worry — the process is f Airly straightforward! You can call Norwegian Air directly at 📞 1-866-284-3022. Whether you are canceling due to personal reasons, weather disruptions, or a change in plans, this guide will walk you through every step. While cancellations can be made online, calling may provide faster support and more detailed assistance.
📍 Step 1: Find Your Flight Information
Before you call or go online, make sure you have the following information ready:
✅ Your booking confirmation number
✅ The name on the reservation
✅ Your flight details (departure date, destination, etc.)
Having this information handy will make the process quicker, especially if you are speaking with a Norwegian Air representative at 📞 1-866-284-3022.
📞 Step 2: Call Norwegian Air Customer Support
The easiest and most direct way to cancel your flight is by calling Norwegian Air customer service at 1-866-284-3022. This line is available to assist with cancellations, modifications, and refund requests.
🧑💼 When you call:
You will be prompted to enter your confirmation number
Select the option for "existing reservation"
Ask to speak to a live representative if needed
Pro tip: Call during off-peak hours (early mornings or late evenings) to avoid long wait times.
🌐 Step 3: Cancel Online (Alternative Option)
If you prefer to cancel online, follow these steps:
Go to the official Norwegian Air website
Click on "My Trips" at the top of the homepage
Enter your last name and confirmation code
Find the reservation you want to cancel
Click on “Cancel” and follow the on-screen instructions
However, if you run into any issues or if your fare type does not allow online cancellations, don’t hesitate to call 1-866-284-3022 for support.
💸 Step 4: Check for Refund or Credit Eligibility
Norwegian Air is a low-cost carrier, and refund policies can vary depending on the fare type. Here is a quick breakdown:
🟢 WORKS Bundle or Refundable Tickets: Eligible for a full refund
🟡 Standard Tickets: May not be refundable but can be canceled for a credit (valid for 90 days)
🔴 Basic Fare or Promo Tickets: Often non-refundable
To clarify your eligibility, it is best to speak to a Vietnam representative directly at 📞 1-866-284-3022. They can explain whether you will receive a refund, a travel credit, or incur a cancellation fee.
⏱️ Step 5: Cancel Within 24 Hours (If Possible)
✅ If you booked your ticket less than 24 hours ago AND your flight is at least 7 days away, you are eligible for a full refund with no cancellation fees.
To take advantage of this policy, it is strongly advised to call 1-866-284-3022 right away and notify them that you fall within the 24-hour window.
📧 Step 6: Get Confirmation of Cancellation
Once your flight is canceled, make sure to:
📨 Check your email for a cancellation confirmation
💳 Verify if any refund or credit has been issued to your account
📅 Note the expiration date of any travel credit issued (typically valid for 90 days)
If you have not received confirmation within a few hours, call 📞 1-866-284-3022 again to follow up and ensure your cancellation was processed correctly.
🤔 Need Help? Contact Norwegian Air Again
Vietnam’s website can sometimes be tricky or limited in functionality, especially for special fares or last-minute cancellations. That is why calling customer service at 📞 1-866-284-3022 is always the most reliable option. Their agents can also assist with:
Modifying your travel dates
Applying travel credits
Rebooking future flights
Answering policy-related questions
✍️ Final Thoughts

🧭 Quick Recap:
Prepare your booking info
Try canceling online or via the Vietnam app
For best results, call Vietnam directly at 📞 1-866-284-3022
Check your eligibility for refunds or travel credits
Always get a cancellation confirmation

Hi there, thanks for picking up on this change.
I see there’s 1 regression and 3 fixes, I just want to check are the fixes previous miscompiles?
Thanks,

The Jenkins instance seems to be down. Is there another way to find out
how this was configured? ISTM that liblto_plugin.so may not have been
built.
